Hi,
I think you know this and probably do it right already, can't hurt to repeat
it though.
You have to run the sb-live with 48khz sampling frequency to achieve good
performance. I haven't heard of this particular issue but I imagine it's
possible since sb-live does internal resampling...
More probable is perhaps that the card is faulty.
